STEEL PIPE JOINT MECHANISM AND CONNECTION METHOD
PROBLEM TO BE SOLVED: To simplify a connecting structure of a pair of steel pipes and reduce cost.SOLUTION: A joint mechanism of a pair of steel pipe piles 1A, 1B comprises inner joints 10A, 10B and an exterior joint 20 that is installed around the inner joints. An inward key part 23, which engages with outward peripheral grooves 13 of the inner joints 10A, 10B, is formed on the exterior joint 20. The exterior joint 20 comprises multiple unit members 21 which are arranged in parallel around the inner joints 10A, 10B. A standard unit member 21A has an engaging convexity 24. An engaging concavity 14, which engages with the engaging convexity 24 and prevents the standard unit member 21A from falling off outward, is formed on the inner joints 10A, 10B. Cutout parts 15A, 15B into which the standard unit member 21A can be inserted to a position where the engaging convexity 24 can engage with the engaging concavity 14, are formed on a wall surface composing the engaging concavity 14.SELECTED DRAWING: Figure 1
【課題】一対の鋼管を連結する構成の簡素化と、コストの低減を図る。【解決手段】一対の鋼管杭１Ａ，１Ｂの継手機構は、内側継手１０Ａ，１０Ｂと、それらに跨って周設される外側継手２０とを備え、外側継手２０には内側継手１０Ａ，１０Ｂの外向き周溝１３と係合する内向きキー部２３が備えられるとともに、外側継手２０は内側継手１０Ａ，１０Ｂの周囲に並設される複数の単位部材２１から構成され、標準単位部材２１Ａは係合凸部２４を備え、内側継手１０Ａ，１０Ｂには係合凸部２４と係合して標準単位部材２１Ａの外方への脱落を防止する係合凹部１４が備えられ、係合凹部１４を構成する壁面には、標準単位部材２１Ａを係合凸部２４が係合凹部１４に係合可能な位置まで挿通可能な切欠部１５Ａ，１５Ｂが備えられている。【選択図】図１
